Summary: Threads and output

Initial Comment:
Hello,

If a thread writes output (into sys.stdin) while a

command should be executed, the command you tried to

execute never finishes executing, so you are stuck.

For example, type this:



>>> from threading import Thread

>>> def f():

	for i in range(200):

		print i,

>>> t = Thread(target=f)

>>> t.start()



Now, while the numbers are showing, type Enter. After

the numbers stopped showing, you'll notive that you

can't execute anything, until you restart the shell.



I noticed this because I wrote a function which

executes at a seperate thread and writes to sys.stderr.

If I try to execute something while the output is being

printed, I get stuck.



Bye,

Noam
